The I2S section is also missing support for enabling an external I2S clock.

[size=13.63636302948px]try to add the following codec to enable I2s0 clk in rk30_i2s.c :

   i2s->clk_i2s_2ch_out = clk_get(&pdev->dev, "clk_i2s_2ch_out");
  if (IS_ERR(i2s->clk_i2s_2ch_out)) {
    dev_err(&pdev->dev, "Can't retrieve clk_i2s_2ch_out\n");
    ret = PTR_ERR(i2s->clk_i2s_2ch_out);
    goto err;
  }
    clk_prepare_enable(i2s->clk_i2s_2ch_out);

Is 8 channel i2S accessible on external pins in RK3128 like RK3066 and RK3288 ?
